Afternoon all,
I haven't seen much tech talk lately so I thought I would post a
couple of questions that have been bugging me and something really neat
I just found. First for the questions.
Question 1) No matter what I do, I cannot get rlogin to work on Mandrake
7.1. The machine is running NIS and I can telnet into any account, but
for the life of me I cannot get rlogin to work. the rsh package is
installed but still no joy. There are no error messages in the logs.
Nothing. The clients connecting just time out. What am I doing wrong?
Question 2) (same machine) I am running on a Dual P-Pro 200 system and I
would like to be able to look at the system load on each processor
separately. How can I do this? Top lists a the average for each cpu. So
does vmstat. I know that there is a command to do this some where, but I
cannot find it. I also know that there is a way to see this information
in the /proc directory, but I have yet to stumble on it. Help.
Question 3) How can I assign a specific process to a specific CPU? Say I
want the system to function on CPU1 and I want a specific process say
nastran to run on CPU2? Is there a way to bind a process to a specific
CPU every time? Can I keep other processes from attempting to use this
CPU? Where can I read more on how Linux uses multiprocessor machines? I
am looking at setting up a dual Xeon 900mHz box and I really would like
to be able to control what CPU is doing what.
Tidbits - in my stumblings on my Redhat 7.0 box I found the following:
In the /etc/sysconfig directory there is a harddisks file. This file
allows you to setup how your system is accessing your hard drives.
Basically it is just a options file for hdparm command, that is run at
boot time. Very slick.
Well that is it for me.
TIA,
Garl
